Bill Gates, the founder and former chairman of Microsoft, has made education-related philanthropy a major focus since stepping down from his day-to-day role in the company in 2008.

His new area of interest: helping solve schools’ money problems. In a speech on Friday, Mr. Gates — who is gaining considerable clout in education circles — plans to urge the 50 state superintendents of education to take difficult steps to restructure the nation’s public education budgets, which have come under severe pressure in the economic downturn.

He suggests they end teacher pay increases based on seniority and on master’s degrees, which he says are unrelated to teachers’ ability to raise student achievement. He also urges an end to efforts to reduce class sizes. Instead, he suggests rewarding the most effective teachers with higher pay for taking on larger classes or teaching in needy schools.
